Package of 10!

New old stock (NOS), unused, genuine part: Philips HEF4541BP Programmable Timer, DIP-14 package.

Manufacturer: Philips
Manufacturer Part Number: HEF4541BP
Product Category: Clock & Timer ICs, Timers
Logic Family: CD4000 (CD4541)
Type: Programmable
Number of Internal Timers: 1 Timer
Package / Case: PDIP-14, Plastic
RoHS: NO
Packaging: Anti-Static

Description
The HEF4541B is a programmable timer which consists of a 16-stage binary counter, an integrated oscillator to be used with external timing components, an automatic power-on reset and output control logic. The frequency of the oscillator is determined by the external components Rt and Ct within the frequency range 1 Hz to 100 kHz. This oscillator may be replaced by an external clock signal at input RS, the timer advances on the positive-going transition of RS. A LOW on the auto reset input (AR) and a LOW on the master reset input (MR) enables the internal power-on reset. A HIGH level at input MR resets the counter independent on all other inputs. Resetting disables the oscillator to provide no active power dissipation.

A HIGH at input AR turns off the power-on reset to provide a low quiescent power dissipation of the timer. The 16-stage counter divides the oscillator frequency by 28, 210, 213 or 216 depending on the state of the address inputs (A0, A1). The divided oscillator frequency is available at output O. The phase input (PH) features a complementary output signal. If the mode select input (MODE) is LOW or HIGH the timer can be used respectively as a single transition timer or 2n frequency divider.
